Why Choose the Carlo Gavazzi S142BRNT924 Photoelectric Sensor Amplifier?

The Carlo Gavazzi S142BRNT924 is a versatile single-channel photoelectric sensor amplifier with integrated timer designed for use with Carlo Gavazzi through-beam photoelectric sensors. As part of the Carlo Gavazzi S142 series, it combines reliable sensor signal processing, adjustable sensing distance and diagnostic functionality for industrial automation and machine-control applications.

The S142BRNT924 is designed for through-beam sensing systems with ranges of up to 50,000 mm. Its integrated adjustable time-delay function provides additional control flexibility, while sensor diagnostics, alignment assistance and adjustable sensitivity help simplify commissioning and maintain dependable detection in industrial environments.

Operating from a 24 V AC/DC supply, the S142BRNT924 provides an SPDT relay output together with an NPN transistor output or alarm function. An emitter mute/test input provides additional control and diagnostic capability, while the compact 11-pole plug-in design enables straightforward installation in industrial control panels.

Reliable Timed Photoelectric Detection for Industrial Automation

Photoelectric amplifiers such as the Carlo Gavazzi S142BRNT924 process signals from separate through-beam sensing heads and provide switching signals for relays, PLCs and machine-control systems. This arrangement allows compact sensing heads to be positioned at the detection point while adjustment, diagnostics and output switching remain conveniently accessible within the control system.

The S142BRNT924 adds an adjustable time-delay function to the S142 amplifier platform, making it suitable for applications where the output must remain active, switch after a delay or accommodate short detection events. Combined with sensor diagnostics, alignment assistance, adjustable sensing distance and flexible relay/NPN outputs, it provides a practical solution for demanding industrial sensing applications.

Typical Applications

  • Industrial through-beam photoelectric sensing systems.
  • Conveyor and material handling equipment.
  • Packaging and production machinery.
  • Timed object and presence detection.
  • Automated assembly and manufacturing equipment.
  • Machine control and industrial automation systems.
